INSUIi ATED VI'IREOUS RECEPTAGLEI Specification of Letters Patent. Patented Elam. 16, 1920.

' I Application filed flov'ember. 7, 1918. Serial No. 261,528.

To all whom it may concern Be it known that we, CORTLAND \V. DAVIS and FRANK R, SUNDERLIN, citizens of the.

United states, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Insulated Vitreous Receptacles; and we'do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art tow ich it appertains to make and use'the same. I Our inventionrelates to msula-ted YItIGQUS receptacles, objects thereof beingto render the containersof such receptacles immune,

as far as possible, from external thermal 'influences,"and also td shield themfrom blows and shocks which are incident to transportation and use. The containerof the receptacle is, for sanitary reasons, preferably made of vitreous materiaL'such as glass, and a fur ther object is,therefore, to so construct the inner parts of the receptacle that, when the container is broken, these partsmay be removed therefrom and replaced by new parts.

The remoyability of the container and its associated parts admits of the restoration'of the receptacle by a substitution of new parts.

Referring tothe drawings- I l is anon-vitreous protective'jacket, preferably made of sheet metal, rolledand bent 3 into cylindrical form, the edges of the sheet being overlapped, riveted and soldered toheat insulating material. The film of silver between it and the lini with a downwardly extending gether in a usual manner. t

2 is an inner lining or jacket, and'3 is a silveredvitreous container, between which and the inner lining 2 is -a space for the reception of. a non-heat conducting filling 4, cork, al:

on the container is protected by a suitable coating.

' The jacket 1 is provided with a number ooves 1 which notonly strengthen said of jac et but provide shock insulating spaces 2 The-bottom 5 of the acket 1 is rovided an e 5 which is riveted and soldered .to the ower end of the jacket 1. Surrounding'the lower end of the jacket 1 is a heavy metal ring 6 constituting a support for the entire receptacle.

All annular diaphragm 7 composed of copper, or other yieldable material, is dis- I posed between the lining 2 and the con tainer, 3', at their upper ends. This diaphragm has a cylindrical body portion 7,

1 which it may be secured by solder, and the internal'flange has a deflected edge 7 A collar 8, having an inwardly extending flange 8? at itsupper end and an outwardly extending flange 8 at its lower end, issecured to the neck of the vitreous container by a suitable bonding substance 9. The deflected edge 7' of the diaphragm 7 overlaps the outwardly extending flange 8 of the col-' ]ar 8 and is secured thereto by solder. The flange 8'} is XII-shaped so as ea constitute a gutter which assists in the soldering opera tion. I

The lining 2,c0ntainer 3, the filling 4:, the diaphragm 7 and the collar 8, constitute a removableunit which, if necessary, may be separated from the jacket 1 and replaced by another unit. While the frangible container is so well protected by the environing parts of the device as not to be easily broken,

even if the device is subjected to'rough'handling, it is possible that it may be broken 7 form that it may yield'toexternal shocks without'transmitting the same in an con-' siderable degree to the frangible contamer 3.

' The protective quality of the diaphragm is enhanced by making it of copper or some other yieldable substance which will become.

distorted by a blow, without transmitting much of theenergy of the blow to the container.

The linin 2 is preferably made of some yieldable su stance, such as thin sheet steel coated with lead or tin, the object beingto,"

admit of thewithdrawal of the liningand the associated parts, even though the protective jacket has become deformed to such an extent that, if made of rigid, material, it-

p would revent the withdrawal of such lining. hould there be difliculty in removing the lining by an endwise movement, the broken parts of the container and the fill' then applied directly to the lining in order to free it from any interlocking portions of the protective jacket,

A shock resisting and retaining ringlO i! may firstbe removed, and .a suitable too secured in position by screws extending through holes in a reinforcing band 11 which encircles the upper end of the jacket 1. This shock resisting and retaining ring, not only looks or secures the lining 2 and the container 3 within the protective jacket 1, butoperates to relieve the container .3, to a considerable extent, from the effect of the shocks which instead of reaching it are transmitted from one side of the protective jacket to-the other.

The receptacle is provided with a bail 12,

the ends 12 of which are arranged to oscillate in holes formed in lugs 13 secured to the reinforcing band 11. The ends of the bail are secured by cotter pins 12 which prevent their withdrawal from the holes in the lugs 13.

' insulating substance.

this cover is provlded with a sheath ng 15 The container 3 is provided with a cover 14', the body portion of which consists of a mass of cork 14 or any other suitable heat The inner face of having a flangelb which extends upward around the body of the cover and terminates in an outwardly extending flange 15". The

cover is provided with a protective cap 15 having a downwardly extending flange 15 1 spaced apart a slight distance from the outer edge of theflange 15". .Within and fitting the flange 15 is a sheet metal ring 16 having a flange 16 which is secured to the flange 15 by solder 16 The space between the protective cap 15 and the flange 15 of the sheathing 15 is filled with cork which maybe a continuation of the main body of 'cork for the cover 14:. In assem bling the parts of the cover, the protective cap 14 and the sheathing 15 are forcedtogether by any suitable means, thereby com ring 16. is filled with cork which, when the cover is applied to the receptacle, bears upon the top of the collar 8 to thereby her-- v metically close the container 3. The only contact between the cover and the container is, therefore, through the medium of a substance having lowheat conductivity. The

After the cover is thusheat by conduction, since a gradual loss of heat, even though restricted, will in the courseof a relatively short time materially reduce the temperature of the container and its contents. The under side of the sheathing is concaved, as shown, so that liquid contents of the container when splashing about Within the same may be deflected away from the space between the protective cover and the container.

Theprotective .cap is secured in position by a locking device 17 consisting of a link 17 and a lever 17 oscillating on apivot 17 secured to a'lug 17. A headed p1n-18 secured to the receptacle is adapted to be engaged by the link 17*. The'lever 17 is bent at right angles sothat its free end 17 may i the lever 17 is actuated.

The inner lining 2 is provided with an in ternaliseat 19 sustaining a brace 19 having a diagonal disposition to prevent the inner parts of the'receptacle from moving ,endwise within said jacket.

The-entire receptacle is closed by a cover 20 having a flange 2O snugly, fitting over the reinforcing band 11, the edge of said flange being provided with a bead 20' with which a pivoted clamp 21 is adaptedto-engage. 21 which is adapted to fit said bead 20 The pivot of the clamp 21 is formed by headed rivets 22 whichsloosely fit openings 22 in the lower end of the clamp. A bolt 1 I 23, fixedly secured to the reinforcing band 11 and threaded at its outer end, is engaged by a thumb nut 24 by means of which said clamp may be forced into engagement with the bead 20". The thumb nut 24 is provided with an external central 'depression'24 of suflicient size to receive a head 23 with which the bolt iiiflis provided. The head'2-3 prevents the th b, nut from being entirely removed from the bolt 23, but the depres-* sion in the thumb nut allows the same to be unscrewed to a suflicient extent to release the bead '20" from the groove 21 of the.

' clamp. It is proposed to employ as many sheathing 15 is anchored by means of its flange 15 in the body of cork, and is elsewhere spaced from the container. Furthermore, the flange 15 of the protective cap 15 is always heat insulated from the-collar- 8 and the container 3. It is extremely desirable, in heat insulatedreceptacles, to prevent the loss of: even small quantities of of these pivoted clamps as may be found necessary. 7
